Polyacrylic acid is innoxious. It is soluble in water. People use this PAA polymer in situations of alkaline and high concentration without scale sediment. The PAA polymer solution can disperse the microcrystals or micro sand of calcium carbonate, calcium phosphate, and calcium sulfate.
It is used as a scale inhibitor and dispersant for circulating cool water system, papermaking, weave, dyeing, ceramics, painting, etc.
Polyacrylates can be made into highly absorbent plastics. The polyacrylic acid plastic has the advantages of strong water absorption capacity, no toxicity and no pungent odor; Can be use in baby diapers.
The maximum water absorption of polyacrylate can reach 1200 times. The copolymer of methyl methacrylate and vinyl acetate is hydrolyzed under pressure and converted into heavy and light groups, which can be used to prepare super absorbent plastics. It has high water absorption and water retention.

IRO also supplys 30%, 40% ,60% polyacrylic acid.
As a scale inhibitor and dispersant, people can use polyacrylic acid in circulating cool water systems in power plants. Also in iron & steel factories, chemical fertilizer plants, refineries, and air conditioning systems. Its dosage should be in accordance with water quality and equipment materials. When workers use PAA polymer alone, 1-15 mg/L is preferred.
People use polyacrylic acid and its derivatives inside throw-away baby diapers. Also in ion exchange resins, adhesives, and cleaning agents widely.
By the way, cleaning agents are copolymers of acrylic acid in many cases. Engineers also use acrylic acid copolymers in both zeolites and phosphates in washing powder products.
This PAA polymer may inactivate the antiseptic chlorhexidine gluconate. And the neutralized polyacrylic acid gels are usually appropriate to acquire biocompatible matrices. That is for healthcare purposes. Such as skin gels for skincare or skin disease treatment products.
For the development of polymeric matrices that allow a controlled delivery rate of active substances. The latest research aimed towards the following clarification.
The conformational changes of the polymeric gel during neutralization, light irradiation, and embedment of gold nanoparticles.
Meanwhile, the US Food and Drug Administration authorized the use of SAPs in packaging with indirect food contact.
200L plastic drum, IBC (1000L). Also as customers’ requirements. Storage for one year in shady room and dry place.
Acidity, avoid contact with eye and skin. Once contacted, flush with water.
